Answer:
G.
Step-by-step explanation:
Since the y-int is (0, 4), you know you have to have an equation that has a +4 in it. When you calculate for the slope, you should get 4/3, and so the only equation that has those 2 is G.
 
        
             
        
        
        
I assume that if we write the equation in its mathematical form it will appear like this:
                                  T = 50 + (N - 40)/4
Substituting the value of T given,
                                  58 = 50 + (N-40)/4
The value of N from the generated equation above is equal to 72. Therefore, the Snowy Tree Crickets chirp 72 times per minute at a temperature of 58°F.
        
                    
             
        
        
        


Substitute 51/5x into 

Substitute that into 

Hope this helps. Answer should be correct. Unless your quadratic equation is wrongly stated.
 
        
             
        
        
        
Answer:
y = 6x + 0
Step-by-step explanation:
Equation of a line 
y = mx + c
Given 
( 0 , 0) ( -1/2 , -3)
find the slope m 
m = y2 - y1 / x2 - x1
x1 = 0
y1 = 0
x2 = -1/2
y2 = -3
Insert the values 
m = y2 - y1 / x2 - x1
m = -3 - 0 / -1/2 - 0
 = -3/-1/2
Minus cancels minus 
 = 3/1/2
 = 3/1 ÷ 1/2
 = 3/1 × 2/1
 = 6/1
 = 6
m = 6
Substitute any of the two points given into the equation of a line 
y = mx + c
Where 
y - intercept point y 
x - intercept point x 
m - slope of the line 
c - intercept 
(-1/2 , -3)
x = -1/2
y = -3
-3 = 6(-1/2) + c
-3 = -6/2 + c
-3 = -3 + c
-3 + 3 = c
c = 0
y = 6x + 0
The equation of the line is 
y = 6x + 0
